how not to always open new tab

Hi, Can you share more details about the issue you're experiencing? Without more details, there's not much we can do to help. If you are referring to links opening in new tabs, try the following: head to Firefox ''Settings'', scroll down to ''Tabs'' (in the ''General'' panel) and uncheck "'''When you open a link, image or media in a new tab, switch to it immediately'''". Looking forward to your update!
